HTML5test
HTML5test is a web application for evaluating a web browser's accuracy in implementing the web standards HTML5 and Web SQL Database (developed by the World Wide Web Consortium), as well as the WebGL standard (developed by the Mozilla Foundation and the Khronos Group). The test suite was developed by Dutch web programmer Niels Leenheer, and published in March 2010. To test a web browser, the user must visit the home page of the website which is located at html5test.com. The application returns an integer score out of a possible 555 points. The point total has changed multiple times through the evolution of the software; Leenheer introduced the present scoring system as part of a major redesign of the test introduced in November 2013. HTML5test evaluates the browser's support for Web storage, the W3C Geolocation API, HTML5-specific HTML elements (including the canvas element), and other features. It does not evaluate a browser's conformance to other web standards, such as Ca ...

Microsoft Edge
Microsoft Edge is a proprietary, cross-platform web browser created by Microsoft. It was first released in 2015 as part of Windows 10 and Xbox One and later ported to other platforms as a fork of Google's Chromium open-source project: Android and iOS, macOS, older Windows versions (Windows 7 and later), and most recently Linux. It was created as the successor to Internet Explorer (IE). Edge was initially built with Microsoft's own proprietary browser engine, EdgeHTML, and their Chakra JavaScript engine. In late 2018, it was announced that Edge would be completely rebuilt as a Chromium-based browser with Blink and V8 engines. The new Edge was publicly released in January 2020, and on Xbox platforms in 2021. Microsoft has since terminated security support for the original browser (now referred to as Microsoft Edge Legacy), and in Windows 11 it is the default web browser (for compatibility with Google Chrome). In May 2022, according to StatCounter, Microsoft Edge became the se ...

WebGL
WebGL (Short for Web Graphics Library) is a JavaScript API for rendering interactive 2D and 3D graphics within any compatible web browser without the use of plug-ins. WebGL is fully integrated with other web standards, allowing GPU-accelerated usage of physics and image processing and effects as part of the web page canvas. WebGL elements can be mixed with other HTML elements and composited with other parts of the page or page background. WebGL programs consist of control code written in JavaScript and shader code that is written in OpenGL ES Shading Language (GLSL ES), a language similar to C or C++, and is executed on a computer's graphics processing unit (GPU). WebGL is designed and maintained by the non-profit Khronos Group. On February 9, 2022 Khronos Group announced WebGL 2.0 support for all major browsers. Design WebGL 1.0 is based on OpenGL ES 2.0 and provides an API for 3D graphics. It uses the HTML5 canvas element and is accessed using Document Object Model (DOM ...

GNOME Web
GNOME Web, called Epiphany until 2012 and still known by that code name, is a free and open-source web browser based on the GTK port of Apple's WebKit rendering engine, called WebKitGTK. It is developed by the GNOME project for Unix-like systems. It is the default and official web browser of GNOME, and part of the GNOME Core Applications. Despite being a component of GNOME, Web has no dependency on GNOME components, so it can be potentially installed on any system supporting GTK and WebKitGTK. GNOME Web is the default web browser on elementary OS and Bodhi Linux version 5. History Naming GNOME Web was originally named "Epiphany", but was rebranded in 2012 as part of GNOME 3.4. The name Epiphany is still used internally, as its code name, for development and in the source code. The package remains ''epiphany-browser'' in Debian (to avoid a name collision with a video game that is also called "Epiphany") and ''epiphany'' in Fedora. Development Galeon Marco Pesenti G ...

Opera (web Browser)
Opera is a multi-platform web browser developed by its namesake company Opera. The browser is based on Chromium, but distinguishes itself from other Chromium-based browsers ( Chrome, Edge, etc.) through its user interface and other features. Opera was initially released on 10 April 1995, making it one of the oldest desktop web browsers still actively developed. It was commercial software for its first ten years and had its own proprietary layout engine, Presto. In 2013, it switched from the Presto engine to Chromium. Opera is available on Windows, macOS, Linux, Android, and iOS (Safari WebKit engine). There are also mobile versions called Opera Mobile and Opera Mini. Opera users also have access to Opera News, a news app based on an AI platform. The company released a gaming-oriented version of the browser, Opera GX, in 2019, and a blockchain-focused Opera Crypto Browser into public beta in January 2022. History In 1994, Jon Stephenson von Tetzchner and Geir Ivarsøy st ...

Google Chrome
Google Chrome is a cross-platform web browser developed by Google. It was first released in 2008 for Microsoft Windows, built with free software components from Apple WebKit and Mozilla Firefox. Versions were later released for Linux, macOS, iOS, and also for Android, where it is the default browser. The browser is also the main component of ChromeOS, where it serves as the platform for web applications. Most of Chrome's source code comes from Google's free and open-source software project ''Chromium'', but Chrome is licensed as proprietary freeware. WebKit was the original rendering engine, but Google eventually forked it to create the Blink engine; all Chrome variants except iOS now use Blink. , StatCounter estimates that Chrome has a 67% worldwide browser market share (after peaking at 72.38% in November 2018) on personal computers (PC), is most used on tablets (having surpassed Safari), and is also dominant on smartphones and at 65% across all platforms combined. ...

Acid3
The Acid3 test is a web test page from the Web Standards Project that checks a web browser's compliance with elements of various web standards, particularly the Document Object Model (DOM) and JavaScript. If the test is successful, the results of the Acid3 test will display a gradually increasing fraction counter below a series of colored rectangles. The number of subtests passed will indicate the percentage that will be displayed on the screen. This percentage does not represent an actual percentage of conformance as the test does not really keep track of the subtests that were actually started (100 is assumed). Moreover, the browser also has to render the page exactly as the reference page is rendered in the same browser. Like the text of the Acid2 test, the text of the Acid3 reference rendering is not a bitmap, in order to allow for certain differences in font rendering. Acid3 was in development from April 2007, and released on 3 March 2008. The main developer was Ian Hickso ...

HTML Element
An HTML element is a type of HTML (HyperText Markup Language) document component, one of several types of HTML nodes (there are also text nodes, comment nodes and others). The first used version of HTML was written by Tim Berners-Lee in 1993 and there have since been many versions of HTML. The most commonly used version is HTML 4.01, which became official standard in December 1999. An HTML document is composed of a tree of simple HTML nodes, such as text nodes, and HTML elements, which add semantics and formatting to parts of document (e.g., make text bold, organize it into paragraphs, lists and tables, or embed hyperlinks and images). Each element can have HTML attributes specified. Elements can also have content, including other elements and text. Concepts Elements vs. tags As is generally understood, the position of an element is indicated as spanning from a start tag and is terminated by an end tag. This is the case for many, but not all, elements within an HTML docume ...

Mozilla Firefox
Mozilla Firefox, or simply Firefox, is a free and open-source web browser developed by the Mozilla Foundation and its subsidiary, the Mozilla Corporation. It uses the Gecko rendering engine to display web pages, which implements current and anticipated web standards. In November 2017, Firefox began incorporating new technology under the code name "Quantum" to promote parallelism and a more intuitive user interface. Firefox is available for Windows 7 and later versions, macOS, and Linux. Its unofficial ports are available for various Unix and Unix-like operating systems, including FreeBSD, OpenBSD, NetBSD, illumos, and Solaris Unix. It is also available for Android and iOS. However, as with all other iOS web browsers, the iOS version uses the WebKit layout engine instead of Gecko due to platform requirements. An optimized version is also available on the Amazon Fire TV as one of the two main browsers available with Amazon's Silk Browser. Firefox was created in 2002 under t ...

Falkon
Falkon (formerly QupZilla) is a free and open-source web browser developed by KDE. It is built on the QtWebEngine, which is a wrapper for the Chromium browser core. Both KaOS and openMandriva Lx use Falkon as their default browser. Features Falkon provides several icon sets and other elements to match the native look and feel of users' desktop operating systems. Some additional features of the browser include the integration of history, web feeds and bookmarks in a single location, the ability to take a screenshot of the entire page, and an Opera-like "''Speed dial''" home page. It is reported to consume fewer system resources than the major general purpose browsers like Firefox and Google Chrome. Falkon uses the Qt cross-platform application framework and offers a built-in AdBlock. By default this adblocker whitelists the web page of Falkon's main search engine, DuckDuckGo. A "portable" (no installation) version for Windows platforms exists. Falkon is also distribut ...

Web Standards Project
The Web Standards Project (WaSP) was a group of professional web developers dedicated to disseminating and encouraging the use of the web standards recommended by the World Wide Web Consortium, along with other groups and standards bodies. Founded in 1998, The Web Standards Project campaigned for standards that reduced the cost and complexity of development while increasing the accessibility and long-term viability of any document published on the Web. WaSP worked with browser companies, authoring tool makers, and peers to encourage them to use these standards, since they "are carefully designed to deliver the greatest benefits to the greatest number of web users". The group disbanded in 2013. Organization The Web Standards Project began as a grassroots coalition "fighting for standards in our ebbrowsers" founded by George Olsen, Glenn Davis, and Jeffrey Zeldman in August 1998. By 2001, the group had achieved its primary goal of persuading Microsoft, Netscape, Opera, and oth ...

Document Object Model
The Document Object Model (DOM) is a cross-platform and language-independent interface that treats an XML or HTML document as a tree structure wherein each node is an object representing a part of the document. The DOM represents a document with a logical tree. Each branch of the tree ends in a node, and each node contains objects. DOM methods allow programmatic access to the tree; with them one can change the structure, style or content of a document. Nodes can have event handlers attached to them. Once an event is triggered, the event handlers get executed. The principal standardization of the DOM was handled by the World Wide Web Consortium (W3C), which last developed a recommendation in 2004. WHATWG took over the development of the standard, publishing it as a living document. The W3C now publishes stable snapshots of the WHATWG standard. In HTML DOM (Document Object Model), every element is a node: * A document is a document node. * All HTML elements are element nodes. * ...
